CanadaWhat does 'best interests of the child' mean when deciding custody?
In Canada, 'best interests of the child' means the court must focus solely on what meets the child’s physical, emotional, and developmental needs — not the parents’ wishes — when making custody (parenting) decisions.
What the Law Says
The federal Divorce Act sets the legal standard for parenting decisions in divorce cases across Canada. It requires courts to consider only the child’s best interests — nothing else.
This means judges cannot prioritize a parent’s preferences, convenience, or even past conduct unless it directly affects the child’s well-being. The law directs attention to the child’s actual needs — such as safety, stability, emotional support, education, and cultural or linguistic continuity — and each parent’s realistic ability to meet them.
The test is forward-looking and child-centred: it asks what arrangement will best support the child’s growth and development over time, not who 'deserves' custody more.
Statutory TextThe court shall consider only the best interests of the child when making parenting orders, considering the child's needs and each parent's ability to meet them.
— Divorce Act, s. 16.1 — Best interests of child
What Courts Have Said
The Supreme Court of Canada has clarified that 'best interests' is a flexible, holistic standard — not a checklist — and must be applied with sensitivity to the child’s unique circumstances.
The Court held that restrictions on a non-custodial parent’s religious expression during access must be justified by clear evidence of harm to the child — reaffirming that 'best interests' requires concrete, child-focused analysis, not assumptions or parental conflict.
What to Do
Focus your arguments on your child’s specific needs — e.g., routine, school, health, relationships — not your own grievances or wishes.
Provide clear evidence of how you meet (or can meet) those needs — e.g., stable housing, involvement in school, consistency in care.
Avoid blaming the other parent unless you can show direct, documented impact on the child’s well-being.
Be open to parenting arrangements that prioritize the child’s voice and evolving needs — especially as they grow older.
